IMPROVEMENT IN CRNCULTIVATORS.

Specificatin formirg part of Letters Patent No. 164,960, datcd June 29, 1875; application filed April 24, 1875.

T0 all whom tt may concern:

Be it known th at I, ALEXANDER F. BALGHEL- LEB, of Cedar Falls, in the county of Black Hawk and State of Iowa, have invented a new and valuable Improvement in Corn-Cultivators; and I do hereby declare that the follow.- ing is afull, clear, and exact description of the construction and operation of the same, reference being had to the anuexed drawin gs, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawin gs is a represen tatiou of a longitudinal vertical section of my cultivator; and Figs. 2 and 3 are detail views of the same. I ig. 4 is a plan view, and Fig. 5 detail view.

The object of my invention is to improve the corn-cultivator for which Letters Patent of the United States were granted to me on the 17th day of October, 1874, as follows:

In the annexed drawings, A A designate two driving and transporting wheels, which are fast on short axles a a, which axles turn in the vertical portions b b of an arched axle, B, and have large bevcled spur-wheels a a on their inner ends. 0 designates a rectangular frame, which extends for'ward 'and in rear of the axle. Upon the rear cross-bar of frame G a drivers seat, C, is pivted, and to the front cross-bar the rear bifurcated portions D of a draft-pole are pivoted, so, that the draft-pole can be moved to the right or left hand. The rear extremities of the bifurcated portions D are connected by loops c 0 to a guide-rod, e, which is secured by its ends to frame C, and which is concentric to the pvot of the draftpole. D designatcs a rectangular frame, which is rigidly secured to the bifurcated portion D, and to the vertical portions of which frame the front ends of two handlcs, E E, are pivoted, so that they caube adjusted both vertically and longitudinally, as circumstances require. FrameD is sustained against backward strain by means.of brace-rods dd, and to the lower extremities of this frame rods c are pivoted, which rods are attached to two blades, F, designed for protectingyoung plants from injury by clods of earth being thrown on them. Blades F are connected together by an arch, F, to which a suspension-rod, f, is attached. Rod f is hooked upon a longitudinal braco, f which is fastened to-the pvot of the draft- )ole in front, and passed through one of a number of holes in a pendant, f fastened to the axle B. The rod f allows the blades F to rise anddescend, and accommodate themselves to inequalitics of surface passed over. The wheels a a eugage with pinions g g, which are applied on vertical spindles Gr Gr, carrying on their lower ends plows h. Wheels g are con nected to their spindles by feathers and grooves, which allow the spindles to be raised or lowered whilethey are rotating. The wheelsg have annular hubs on them, which are embraced by yokes 2' that rest on arms j, through which the spindles Gr pass freely. The arms j are free to slide laterally on long staples 2, fastened, to the under side of the axle B, and sustaiued by means of yokes 3, which are also adjustable with the arms. The lower ends of the spiudle pass through guides k fastened to the lower ends of the vertical portions b of the axle B. Shafts o a are secured by keys or other means to their wheels A A, by looseniug which keys the axles are endwise adjustahle. By these means the two sets of plows h can be adjusted nearer to or farther from each other, as may be required. The

plows or shovels h are secured to arms, which are ri gidly fastened to hubs l, which latter are adjustably secured to the lower ends of the spindles Gr.- The drawing represents three plows attached to each spindle, but a greater or less number may be employed. The handles E E extend back as far as the drivers seat, and are suspended from the axle B by means of linksn, which are attached to 'rods o that pass vertically through the axle, and have heads ou their upper ends, between which and the axle springs s are applied. The springs s sustain the handles, and allow them to be depressed for lowering the spindles, to which they are connected by means of arms having eyes on them receiving annular grooved portions of the spindles. By these means the driver can raise or lower the plows from his seat O. The vertical portions of the arms m, to which the plows h are secured have rollers p on them, which are designed for clearing the plows of anything which accumulates on them. This is done by means of tooth ed segments J, which are secured to arms depending from the han- (es E, and which are so airrtnged that when the plows areraisedhigh enough the segmeuts J will give rapid rotation to the rollers or 2. Handles E, adjnstably pivoted to frame D, und connected to the spindles Gr, in combinzttion with the suspensionlinks u, rods o, and spring s, substantially as described.

3. 111 combination with the revolving p1ows IL, the rolling-clearers p, and the segment-rack J, substantially as described.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

ALEXANDER FRELAND BATCHELLER.
